I maintain a store of encrypted data I would like to expose to other applications. Right now the data requires a passcode to unlock/decrypt that data.
The document provider extension I created so far doesn't seem to be loading (I checked the certificates) and I can't expose that to the other apps.
Are there any examples of how to do this?
I've already looked at the official documentation, the Git repository of various team members of Xamarin, and all the other general sources.
Are there any special gotcha's I need to address and may be missing?
This should give you a good start : https://forums.xamarin.com/discussion/16071/encryption-decryption-in-xamarin
And to get a complete working solution. Refer the Kinder Chat app.

I'm trying to find a good alternative at Parse.
FireBase seems to be good, but I can't find how to upload image/file from the dashboard like in Parse ?
Can we upload image/file from the firebase dashboard like in Parse ?
No You Can Not because firebase doesn't provide such type of feature.
Edit:
Ah! My old accepted answer got unaccepted because I gave straight answer :) Well OP didn't ask about programming way of solution so I assumed not to provide one.
There are couple of approaches to handle images with firebase, I usually upload images to s3 bucket and store urls in firebase. Again there is choice to implement above approach i.e. do all on server-side, do all on client-side or do with mix of client-side and server-side. But It is better to do signaturing on server to keep thing secure.
Node-Cheat Available:
For complete code, get working node-cheat at github node-cheat aws, choose any folder and run node file_name.
While the above is an answer, it's does't provide a solution, so here's a bit more data.
Uploading/storing data in firebase is super simple and requires a minimal amount of code.
For images, encode the image as a string and store the string in firebase. Then to retrieve the image, retrieve the string and decode it.
You should be able to do both in about 12 lines of code (depending on platform).
There are several examples already published here, I like this one with Swift.

Hope that helps!
No, you cannot upload directly, but you could use some opensource project out there that will make a simple dashboard for you to upload it easily like this tutorial
I know that someone mean will probably close this question for being opinion, but the truth is, I'm not after opinion as such, but actual facts about the correct way and how to do this.
I've been searching around for quite a time and I'm still unclear as to what direction to take. It seems there are a billion* libraries that I could use, but I want to know what would be the correct, proper supported method of achieving this.
Essentially, I have a very simple requirement to list and download files from Sites on our Office 365 subscription to an iOS application.
Initially, I looked at the REST interface for Sharepoint and, from a browser, was able to easily perform a GET to our site and receive and receie a response with meta data about the file, for example:
https://mytenantid.sharepoint.com/_api/web/getfilebyserverrelativeurl('/MyFile/Here/Document.txt')
I could also retrieve JSON output instead of XML by specifying an Accept header of application/json using the POSTMAN REST client for Chrome.
So far, so easy. Just the authentication to do outside of the browser and that's it.
Phew!!
I started by looking at Basic authentication, but wasn't sure if this is the right way to do it and even if it would work?
On looking further, it seems that actually, using OAuth might be the way to go. Apparently, you can either do this yourself (no idea how), or use a library (ADAL?) from Microsoft? Unfortunately, this all looks half baked will very little documentation that seems to work. It also requires the use of CocoaPods and workspaces and isn't just a simple library that I can copy to my project and start using (a la SwiftyJSON). There also seems to be a lot of other libraries around too.
I should mention that I'm using Swift, so I've tried converting code from Objective C to Swift (unsuccessfully) too. Apparently I can't use "readWithCallback" with an argument list that the code tells me I should actually use -- even a sample application I downloaded had the same issue.
I've also tried using node.js with a script (not a Web Application) and the documentation and number of libraries available for that is almost worse.
Any assistance to achieve this really simple capability would be hugely appreciated -- it's been driving me nuts.
Many thanks,
D.
*this might be a slight exaggeration.
Office 365 has a RESTful API that you can use any programming language to authentication and integrate in your app.
Here is a simple example for iOS connected app to office 365. The sample shows how to do this in Objective C and SWIFT.

I was wondering if anyone could point me to any useful tutorials on allowing a master user to update information for their app. I am looking into creating an application for a local restaurant and I want the owner to be able to update information like the soup of the day and such by themselves.
I have been looking into JSON and CMS for this, but I am unable to find any useful information regarding iOS 8 or xCode 6. If anyone could provide me with this information, or any other suggestions on how to achieve this I would be very grateful!
(I am using Swift not Objective-C)
This is not a code issue, rather it is a development concept issue. You have many choices including making an API that is updated by the restaurant. The app then connects to the API and gets the recipes. If you feel you need to do this via the App make a special username that is allowed access to modify the menu. This can be accomplished via matching username exactly or via using a regex. It all really depends on the structure of your app platform.
I was learning a little more about ios extensions, such as:
Today Extension
Photo editing Extension
Action Extension
Custom keyboard Extension
In all of them I did not have difficulties in learning, but recently I try to learn the "document provider extension", and to my surprise not found any relevant tutorial on the Internet talking about how to use it (step by step as the others).
The only alternative I found was use the documentation, and I learned that he can access shared documents from other applications, and you can also share your own existing documents within your app.
The only tutorial I found on the net was the site MacStories but he use iCloud, and in this time I not want to use iCloud, I want do to like documentation says:
allows other apps to access the documents managed by your app (Without iCloud)
In my case I already know how the "provider document extension" works, and so managed to create a new target type "document provider extention" and only that. Anyone know how this extension work?

or watch the following session from WWDC

Also one of the best could be ios8 by tutorials book on raywanderlich.com but this one is not free
I am also looking for the same. There are not very much good tutorials on this topic. I'll share Some of the links that i have found.

I have been using Parse lately for applications I develop, mainly due to the simplicity of getting an app off the ground. This could eventually be costly, more so unless I store to my own database on a rented server, I'd assume. So my question is: How would I go about storing data externally to my own server? Is there any sort of framework like parse for this with option to use one's own server storage instead? I'd assume theres something considering writing a whole login system etc that's secure multiple times would seem a bit repetitive, hence Parse. Thanks in advance!
Google has provided a mobile backend starter some time ago, here is the link https://developers.google.com/cloud/samples/mbs/. Hope it will help!
Yes you have. Kindly look into DynamoDB from amazon.
Here is a good documentation for iOS SDK.
More granular detail is here
I hope that helps.
You may need to have an account with amazon aws in order to create your appID & all.
